Display panel and display panel system

摘要

A display panel comprises an array of light elements arranged in n rows by m columns. At least one driver is configured to drive one of said columns and rows, wherein the or each driver is configured to drive each of said columns or said rows. A plurality of the display panels may be used together to form a display panel system.

1. A display panel comprising:
an array of light elements arranged in n rows by m columns; a controller configured to provide first drive data and second drive data, at least one driver configured to directly drive a first one of said m columns or said n rows, wherein the controller is further configured to provide control signals directly to the at least one driver of the display panel and directly to a panel output, and wherein the controller is further configured to provide the control signals through the panel output to at least one second driver in at least one other panel, wherein the control signals include a system clock, at least one pulse width modulation timer clock, and a latch enable signal and are provided separately from the first drive data and the second drive data, wherein the at least one driver is configured to drive each of the first one of said m columns or said n rows using first drive data and according to the control signals received separately from the first drive data, wherein the at least one driver operates with a duty cycle according to the at least one pulse width modulation timer clock, wherein the at least one driver of the display panel is further configured to provide the second drive data by a serial data out (SDO) connection directly to a panel output, and wherein the at least one driver is further configured to provide the second drive data through the panel output to at the least one second driver in at the least one other panel; and a plurality of MOSFETs, each of the plurality of MOSFETs connected to a respective first end of a second one of the m columns or n rows; wherein a second end of each of the second one of the m columns or n rows is connected directly to the panel output separately from the SDO connection; and wherein each of the plurality of MOSFETs is configured to control a row control signal and propagate the row control signal through a respective one of the second one of the m columns or n rows of the display panel, and through the panel output to the at least one other panel.
